- What is the difference between void type pointer and simple pointer? Use C++ programpointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.Task related to pointers : Write a c++ program that asks the user to enter integers as inputs to be stored in the variables 'a' and 'b' respectively. There are also two integer pointers named ptrA and ptrB. Assign the values of 'a' and 'b' to ptrA and ptrB respectively, and display them. ( Drop code in words , explain the code and drop the screenshot of output as well )
- what is the difference between void type pointer amd simple pointer?Month Day Calculator in C Using basic concepts of Pointers and Structures (Pointers and Multi-dimensional arrays), create a C program that calculates the month's day from a given year and year's day. Use pointers for the month and month's day variables. Don't forget to add proper errors handling in your program. - Follow the instructions below for handling error. - Invalid Input- Invalid year- Invalid year day Modify the provided monthAndDay.c class file to receive the parameters in the way and also print the proper formatted output. Example: # ./month_day <year> <yearday> # Example for Feb 2nd, 2019:\$ ./month-day 2019 33Feb 02, 2019 class- monthAndDay.c - #include <stdio.h> /* monthAndDay function's prototype*/void monthAndDay(int year, int yearday, int *pmonth, int *pday); int main() {return 0;}Create a program in C language that calculates the month's day from a given year and year's day. Use pointers for the month and month's day variables. Don't forget to add proper errors handling in your program. Example or errors - Invalid Input- Invalid year- Invalid year day Example of input # ./month_day <year> <yearday> # Example for Feb 2nd, 2019:\$ ./month-day 2019 33Feb 02, 2019 I have this class - month-day.c - #include <stdio.h> /* month_day function's prototype*/void month_day(int year, int yearday, int *pmonth, int *pday); int main() {return 0;} Note: I don't need the calendar, please read the instructions well!!
- Example: Write a C++ program that calculates the sum and average of an initialized integer array. #include using namespace std;c++ programming language given the following variable declaration: double avg; write the required commands to declare a pointer, and then use it to display the value of the variable avg.In C++, variables that store floating point numbers are declared as either float or double. Describe floating point numbers. Explain the difference(s) between float or double data types.
